This Python program can analyze Blockland memory dumps (MDMP) and is also able to print TraceBuddy traces in that same memory dump.
Memory dumps (on Windows) are created by using Task Manager and right-clicking on the relevant process and clicking "Create memory dump file".

Much of the memory layout is known or derived from other projects, particularly libBLstructs, so many of the same techniques and layouts will appear here as they do there.

Make sure to use a recent version of TraceBuddy (>= 2.1.0, November 2023) or use `--help-offsets` to work with memory dumps with older versions of TraceBuddy.
TraceBuddy now prints the location of its trace_lines std::list in console.log; read the console.log for the offset if the default `0x100034` does not work.


Classes for which positions are printed are defined in dump-examine.py near the top:
`classes_interest = ['fxDTSBrick', 'AIPlayer', 'Player', 'WheeledVehicle', 'FlyingVehicle', 'HoverVehicle']`


Dump every object in game and print TraceBuddy lines:
`python3 dump-examine.py dumps/Blockland.DMP --analyze-objects --print-tracebuddy`

Example output:
```
Reading pointer at 0x68280034
trace_lines std::list starts at 0x08be5ed8
Located first element
